Isaiah 54:10

For the mountains shall depart and the hills be removed, although the most awful cataclysms of nature should occur, so that the very foundations of the earth are shaken, but My kindness shall not depart from thee, so that the wonderful union and communion of love between Christ and His Church would be disturbed or disrupted, neither shall the covenant of My peace be removed, that of the Messianic promise, as first given to Abraham and then repeated throughout the Old Testament, saith the Lord that hath mercy on thee. The depth and the certainty of God's love is thus set forth in a manner which makes this promise basic for the faith of all Christians of all times. What was written here is written for our comfort; we should believe these promises and rejoice in them always.
